Plane Destruction

On the ground, the Wolf Riders brandished their scimitars, first cutting their own mounts' necks before cutting their own necks while laughing. 

Kodos, Warlocks, Shamans, Warriors.

The army of over a million Beastmen killed themselves on the prairie. A solemn aura fused with blood and dyed the sky red.

The blood of over a million Beastmen defied gravity and floated towards the sky, forming an even bigger array which ultimately wrapped the entire world. Souls emitting faint light floated out of the corpses. Not a single one hesitated or turned back to merge with the earth.

It was like countless fireflies were floating over the earth and flying towards the sky. Those souls softly cursed and roared.

The whispers of the souls merged together and formed a huge pressure suppressing the Greater Demon Overlord. Over a million Beastmen killed themselves, their faith bursting out at death's door, fully targeting the Greater Demon Overlord.
